Terms of use

Last updated: 21 July 2026

By using FitTools you agree to these terms. If you do not agree, please do not use the site.

What the site provides

FitTools provides calculators and editorial content for general information and education. Results are estimates produced by published formulas and are provided “as is”, without warranty of any kind. The site does not provide medical advice — see the medical disclaimer, which forms part of these terms.

Your responsibilities

You are responsible for how you use the estimates this site produces, including decisions about training loads, diet and recovery. Do not rely on the site for medical decisions, and do not use it where an error in an estimate could cause harm.

Liability

To the fullest extent permitted by law, we exclude liability for any loss or damage arising from use of the site or reliance on its content. Nothing in these terms excludes liability that cannot be excluded under the law of England and Wales, which governs these terms.

Content and intellectual property

Site content, design and code are our intellectual property or used under licence. You may link to any page freely. The published formulas themselves belong to science; our implementations, editorial and presentation belong to us.

Changes

We may update these terms and will change the date above when we do. Continued use after a change constitutes acceptance.
